Job Description Summary:UCAR is excited to announce the job opening for the CPAESS Associate Scientist IV role working with NOAA’s Geophysical Fluid Dynamics Laboratory (GFDL). This position will involve developing methodologies to quantify and map the past and future annual changes in Earth’s Radiation Budget (ERB) using NOAA's state-of-the-art global atmospheric models. In particular, the contributions to the changing solar, longwave, and net radiation budget from anthropogenic and natural drivers will be investigated, on timescales from “beyond weather” or subseasonal to decadal, and how a variety of processes act on the ERB, including regional and seasonal changes. This understanding will contribute to determining the relative importance of the changing atmospheric constituents to Earth’s Radiation Budget.A key responsibility is the development of advanced atmosphere and earth-system models for understanding the impact of changes in aerosol emissions over this period on atmospheric variability, trends, and extreme events. This work will include evaluating the quality of aerosol-cloud interactions within the GFDL atmospheric models to assess the fidelity to capture recent trends. Another key responsibility is the development of other aspects of numerical models to improve processes related to ERB, including resolved and subgrid transport and mixing, atmosphere-surface interactions, and aerosol-cloud-precipitation-radiation interactions. Improving the general scientific quality of the model will greatly increase the accuracy of key ERB processes and enhance the credibility of the model results. CPAESS (Cooperative Programs for the Advancement of Earth System Science) serves the Earth System Science community in three distinct areas of service. We partner with federal agencies and businesses to hire critical scientific staff, enabling a more robust workforce. Through our scientific programs, we seek to edify new research with our postdoctoral programs, our visiting scientists and internship programs, along with our interagency support programs. We also help build the Earth system science community by convening and…
